----------------------------Original message---------------------------- . I should have never responded to your request for information, in that I realize that I have just walked into a hornets nest consisting of flamers. However, I can tell you that there are many people of your profession that have gone into consulting businesses that are geared toward the cartographic world. They use university students, hardware, software and facilities to house their businesses. Additionally, if they pay their students it is at minimum. Most of the times their students are contract. You might want to ask yourself, the next time you are asked to provide an inordinate amount of information about a subject, how the information is going to be used. My first message attempted to convey the thought that the end users of "maps" are getting conflicting information from people who have not done their homework.
